The Rayhigher Keyless Entry Knob Lock is a keypad knob lock that replaces a standard door knob and adds code-based entry. It stores up to 50 codes of 1 to 15 digits, has a backlit keypad with a silent mode, and keeps two mechanical keys as a fallback. It runs on 4 AAA batteries with a low-battery alarm and a USB-C backup power option. It suits rentals, home offices and guest or staff doors where handing out codes beats copying keys; against app-connected smart locks it is simpler and cheaper in features, with no phone control or auto-unlock.

The Rayhigher Keyless Entry Knob Lock pairs a keypad with a knob handle in a black finish. It lets you open a door with a code, and it also works with mechanical keys. It can be used on exterior doors and on interior doors such as bedrooms and closets.
The lock stores up to 50 custom codes, each 1 to 15 digits long. The keypad is backlit so the numbers are visible day or night, and a silent mode reduces keypad noise. Two backup keys are included.
The body is heavy-duty metal with a plating finish and a solid lock cylinder. It has IP65 weather resistance and works in temperatures from -22°F to 176°F. It runs on 4 AAA batteries, gives a low battery alarm, and has a Type-C USB port for backup power.
